gains beyond my expectations

This was my 1st magnum purchase and it did not disappoint, I still duck one star. Fast shipping, a bit lousy packaging, straightforward directions for installation, top notch quality and gains beyond my expectations. The only regret was the kit dose not work in conjunction with my optimizer chip from (removed) so I had to uninstall it, in all other respects I was satisfied.

gave an extra 4 MPG

I bought a fuel economy combo from these guys and in my conclusion it works great mpg wise in addition not only did NOT kill my performance but a little bit improved it. This kit actually has brought my gas mileage back after I added cold intake and gave an extra 4 MPG. Bottomline I recommend it. Great value for your bucks.

gassing up much less fuel

after i set this economizer kit on my old celica with 250,000 mniles on it, i am gassing up much less fuel than before, there is no accurate calculation so its just a rough estaimte but these parts pumped up my economy by at least 15 %, did i lose power? - Nope!!!

I saw some mileage boost and fuel saving

Eco kit arrived promptly and package was as expected, magnum is a good supplier but changes in fuel economy were moderated or considerable MPG increase is a mere pipe dream. I saw some mileage boost and fuel saving that is appreicated but far from the claims advertized. Did notice a huge jump in acceleration though.

moderated level of economy improvement

Delivered right on cue, in good packaging and install it in two hours or a bit less. I see only moderated level of economy improvement only, as opposed to the 16% advertized. Another heads up to everyone, the intake add on requires certain modification of the intake, you have to drill the air filter cleaner's flange. I'm not delighted to perish OEM parts by fabricating. Engine pulls a little better and acceleration slightly improved but the car still remained underpowered.

fuel saver kit seems perfect in all areas

Part shipped sooner than I thought I should get. Have it installed by (removed) garage in (removed) and telling the truth, at the first peek I'm impressed by the extra mileage this kit delivered on my MX6. Havent noticed extra horses but the fuel saver kit seems perfect in all areas. I'd ultimately like to install on the wife's Cadillac too.

saw significant MPG gain

Installed this gas saver combo on my naturally aspirated Cougar and saw significant MPG gain. The lil horsepower gain that was advertized is no exception. I'm confident heaps of company could take the advantage of these parts like taxi companies, public transportation, police, airports. Although gas savers have conducted their job in my car for over years now, thus far there has been no compromise of durability and there are no setbacks at all. Cur runs like before, no check engine light, no bogging, engine revs up a bit better than w/o the kit and idles smooth. My summing up, this wrench-on combo is an easy way to get better mileage and a slight boost of performance. I'm bound I could extract even more from this engine both of economy and performance but my Cougar has 200K+ miles on it so I wouldn't venture to dust it. All in all I'd recommend to friends or family.

I can attest this kit worth every penny

I paired this fuel saver kit with my k&n filter and it works like a charm now I made 5 consecutive tests driving more than 1000 miles and I can attest this kit worth every penny and actually feel a difference in power and throttle response. Totally satisfied. %+ star purchase!
